Copper is very important. I was supplementing just zinc for a long time. I’ve reduced zinc to 3x a week and take copper with it, and also take chlorophyll in the form of copper chlorophyllin 7x a week morning and night.

I’m glad you posted this. It was just this week, when I was hunting for a good zinc lozenge to have on hand in the event I start feeling sick, my friend said make sure you also take copper.
Your post inspired me to look at my multi and I see my daily blueprint capsule contains 15mg of zinc, but alas, no copper.
Do you happen to know if we need to take copper daily to offset it, or is this the kind of thing we could take a couple times per week (trying desperately not to add things to my too big stack! 
The doctor in the video said there are combination zinc/copper supplements available.

Experts range in their recommendation from a ratio of 1:8 to 1:80 for zinc to copper. Whichever you feel most comfortable with.
I also take a multivitamin with 0.5 mg of copper and 11 mg of zinc. So my ratio would be 1:50.
If you want more copper, you can try this:
